WINDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 759,595, dated May 10, 1904.

Application filed December 2, 1903. Serial No. 183,4:82. (No model.)

To all whom it may concern.-

Be it known that I, JOHN P. CRONIN, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in WindingdVIachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to machines for winding cops, bobbins, spools, and the like, and it h as reference especially to winding machinery in which some part is made to bear on the cop as the same is wound in order to promote evenness of winding and compactness in the finished cop.

The invention has for its object to provide a simple and reliable mechanism for throwing the part above mentioned out of contact with the cop when upon the breaking of the thread the necessity for its continued bearing on the cop is removed and such continued contact would, in fact, with the cop remaining in motion, tend to spoil the surface thereof.

In the accompanying drawings, wherein the invention will be found fully illustrated, Figure 1 is a View in front elevation of a winding-machine of the class indicated provided with my improvement. Fig. 2 is an enlarged side view of the upper portion of the machine seen in Fig. 1; and Fig. 3 is a View, partlyin plan and partly in section, of certain parts seen in Figs. 1 and 2.

In a frame a, which comprises a laterally projecting stub-shaft 72, carrying a puppet 0, is journaled the main shaft 0?, adapted to be rotated from a suitable source by a belt 0, which extends over a pulley f on said shaft. At one end of this shaft d and in the puppet 0 is sustained by any suitable expedients and in such manner as to be rotated from the shaft a spool, cop-tube, or the like 9.

In frame a is arranged to reciprocate a rod It, the same being actuated from a rotary cam 2', engaged by a suitable part j, carried by red it. Cam i is rotated through gearing 7r; 5 from a shaft Z, which is in turn driven from shaft (Z by a belt m, passing over pulleys n on shafts d and Z.

The mechanism so far described comprises means for rotating the bobbin and for simultaneously reciprocating or traversing the thread-guide (now to be described) and is all substantially what may be found in the United i States patent to S. W. VVardwell, Jr., No. 589,587.

On the rod It is secured by a clamping-screw 0 a split block 1), and also on said rod is fulcrumed the thread-guide q, the same having its lower end bent around rod it to form the fulcrum and divided or forked, receiving in its forked portion the block which thus acts to prevent sidewise movement of the thread-guide.

The above statement of construction and function of part 10 sets forth all that can be 7 said of said part, so far as its pertinency to the present invention is concerned, so further description thereof is unnecessary.

r is a slide carrying the thread-eyelets and adjustably secured to the front face of the thread-guide between lugst by a set-screw a. The upper end of the thread-guide is formed with a bearing-piece o, adapted to bear against the cop being Wound, under the pull of the thread, to promote evenness of winding and compactness in the finished cop, said upper end of the thread-guide and the bearing-piecebeing formed with a slit 4/; for the reception of the thread 00 in the portion thereof between the cop and the eyelet s. In the upper end of 5 the thread-guide is pivoted an arm 9 having its upper end .2 hooked to receive the thread and its lower end .2 extending substantially horizontal. The swinging movement of this part is limited by pins I, mounted in the 9 thread-guide and disposed each side of said arm. The thread normally holds the arm in the position shown in Fig. 1 a, against the left-hand pin; but if the thread breaks said arm will move by the action of gravity and the traversing motion of the threadguide toward the right-hand pin.

In a block 2, secured to the inside face of the puppet 0 by a screw 3, is arranged to slide horizontally a knock-off device 4. Said de vice is normally pulled forwardly by a spiral spring 5, connecting its rear end with the screw, which transversely penetrates the bore 6 of the block occupied by the knock-01f device. Said knock-off device is held in its rearmost position by a trigger 7 consisting of a metallic strip clamped between the block and the puppet c and having a lug 8, taking against the front end of the knock-off device.

9 is an arm forming a part of the knock-off device and extending parallel with the coptube 9 and approximately as far as the threadguide has traverse.

10 is a thumb-piece or handle for pressing back the knock-off device to reset the same.

In operation the pull of the thread keeps arm 3/ in the position shown in Fig. 1. At this time the knoclcofi device is held back, as shown in Fig. 3, against the tension of spring 5 by the trigger 7. As the thread-guide reciprocates with rod 7L, arm 3/ being held in the position above described, the part 2 thereof is out of position to engage the trigger 7. (See Fig. 2.) Should, however, the thread break or slacken, arm 3 will move to the right, and its part 2' being now in alinement with the trigger the next time the threadguide moves to the right said part 2 of the arm will engage the trigger and push the same into the dotted-line position shown in Fig. 3, (the puppet 0 having a recess 0' to receive the trigger when in this position,) whereupon the knock-off device will be released and thrown forward by its spring 5, its arm 9 inipinging against the thread guide and turning the same outwardly on its fulcrum, so that the bearingpiece '2; will stand clear of the cop. In order to reset the parts, it is only necessary to push against the thumb-piece 10 to force the knockoff device back far enough so that lug 8 of the trigger reengages said knock-off device.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a winding-machine, the combination of the cop-holding means, the thread-guiding means, means for eifecting the rotation of one of the aforesaid means relatively to the other,

said thread-guiding means comprising a part adapted to normally bear against the cop being wound, a normally-restrained self-acting means for moving said part out of contact with the cop, means for effecting a relative reciprocation between the thread -guiding means, on the one hand, and the cop-holding means and said self-acting means, on the other hand, and another part, carried by said threadguiding means, for controlling the release of said self-acting means, said other part being itself controlled by the thread, substantially as described.

2. In a winding-machine, the combination of means for rotating the cop, a reciprocatory thread-guiding means comprising a movable part normally bearing against the cop being wound, a normallyrestrained self acting means for moving said part out of contact with the cop, and another part, carried by said thread-guiding means, for controlling the release of said self-acting means, said other part being itself controlled by the thread, substantially as described.

3. In a winding-machine, the combination of means for rotating the cop, a reciprocatory thread-guiding means comprising a movable part normallybearing against the cop being wound, a normally-restrained self-acting means for moving said part out of contact with the cop, and another part, carried by said first-named part, for controlling the release of said self-acting means, said other part being itself controlled by the thread, substan tially as described.

4:. In a winding-machine, the combination of means for rotating the cop, a reciprocatory thread-guiding means comprising a movable part normally bearing against the cop being wound, a spring-actuated knock-off device movable against said movable part of the thread-guiding means to force the same out of engagement with the cop, a trigger normally holding said device retracted, and a movable arm carried by said thread-guiding means and engageable with said trigger to cause the same to release said knock-off device, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of December, 1903.

JOHN P. CRONIN.
